Respraying a guitar rarely increases the value of a guitar regradless of who's sprayed it. Sadly as soon as they're no longer stock finish the prce takes a hit.

Sorry but I don't agreed, you are right if the guitar would be vintage and collectable that generally have very good parts, while here there is a "new" guitar with cheap finish with horrible color (greenish).

However I accept your opinion but if a 2011 Tokai is sell for 2000 € I don't think that 1000 € for a 2014 Bacchus (paint or not) is too much

Yeah where i'm located refinished guitars (even for the better) are worth less. That's just the way it is here. Same with upgrades, they don't get you any extra $$ in fact, mostly makes the guitar worth less because its been modded. New or old don't matter.
